Composition

The product in the amber glass vial contains IBR, BVD types 1 and 2, PI3, and BRSV modified live viruses. The plastic vial contains an adjuvanted diluent. Neomycin and thimerosal are used as preservatives.

Directions and Dosage: Shake the accompanying bottle of adjuvanted diluent, then rehydrate the modified live virus vaccine by aseptically adding the adjuvanted diluent to the vaccine vial. Shake the rehydrated vaccine and use immediately. Using aseptic technique, inject 2 mL subcutaneously in front of the shoulder and midway of the neck, away from the suprascapular lymph node. If initial vaccination, repeat with any Express® vaccine containing BRSV modified live virus (MLV) in 14-28 days. Calves vaccinated before 6 months of age should be revaccinated at 6 months. A 2 mL booster dose is recommended annually.

Precautions

Store in dark at 2-7°C. Avoid freezing. Use entire contents when first opened. Do not vaccinate within 21 days before slaughter. Fetal protection has not been demonstrated with this product. Stressed cattle should not be vaccinated. Do not use in pregnant cows or in calves nursing pregnant cows. Burn vaccine container and all unused contents. Injection site swelling or anaphylactoid reactions may occur. Antidote: Epinephrine.

Note: It is possible that healthy appearing cattle can be persistently infected with or incubating virulent BVD virus at time of vaccination. In view of these findings and suggested causes, BVD vaccine is contraindicated in persistently infected cattle and use should be limited only to healthy, immunocompetent, unstressed, nonpregnant cattle.
